M62.111 Other rupture of muscle (nontraumatic), right shoulder

Name of the Condition

• Other rupture of muscle (nontraumatic), right shoulder

Summary

Other rupture of muscle (nontraumatic), right shoulder refers to the tearing or splitting of muscle fibers in the right shoulder without associated trauma. This condition can disrupt muscle structure and function, potentially leading to pain, weakness, or impaired movement in the affected area.

Causes

The exact cause of nontraumatic muscle rupture is not fully understood. It may involve degenerative changes within the muscle, overuse, underlying systemic conditions, or factors that weaken muscle integrity, such as certain metabolic or connective tissue disorders.

Risk Factors

• Increasing age
• Repetitive or improper muscle use
• Pre-existing muscle or connective tissue disorders
• Certain systemic diseases affecting muscle health
• Use of medications that weaken muscle (e.g., corticosteroids)

Symptoms

• Sudden or gradual onset of pain in the right shoulder
• Weakness or reduced muscle strength in the shoulder
• Visible bulging or deformity in the affected muscle
• Difficulty with shoulder movement or performing tasks
• Possible bruising or swelling

Diagnosis

Diagnosis typically involves a physical examination to assess muscle integrity and function in the right shoulder. Imaging tests such as MRI or ultrasound may be used to visualize muscle structure and confirm rupture. Patient history and activity level are also evaluated to rule out traumatic causes.

Treatment Options

• Rest and avoidance of activities that strain the affected muscle
• Physical therapy to restore strength and flexibility
• Pain management with NSAIDs or other medications
• In severe cases, surgical intervention may be considered

Prognosis and Follow-Up

Prognosis depends on the severity of the rupture and adherence to treatment. Most cases improve with conservative management, but recovery may take several weeks to months. Follow-up may include monitoring for healing and functional recovery.

Complications

• Persistent pain or weakness
• Limited range of motion
• Re-rupture of the muscle
• Chronic disability if untreated

Lifestyle & Prevention

• Avoid overuse or improper lifting techniques
• Maintain muscle strength and flexibility through regular exercise
• Use proper form during physical activities
• Address underlying health conditions that may weaken muscles

When to Seek Professional Help

Seek medical attention if you experience sudden, severe pain in the right shoulder, inability to move the shoulder, visible muscle deformity, or if symptoms worsen despite rest.

Tips for Medical Coders

Document the specific anatomical location (right shoulder) and confirm the nontraumatic nature of the rupture. Ensure clinical notes support the diagnosis and exclude traumatic causes. Code M62.111 is specific to the right shoulder; verify site specificity in documentation.
